[opensuse 13.2] R7 370 installed but can not boot but in recovery mode

Greetings !!

I just installed a R7 370 and now my computer won’t boot unless in recovery mode.
Going to system settings → display configuration I have no description about the video card driver (it was the case with the embedded video card). Same resolution 1920x1080.

Outside the recovery mode I got a reset (after blackscreen)

I dug the Web but never find some efficient workaround… how can I do to fix it ?

Download the catalyst driver for Linux ?

Been there… and downloaded the last version available (all from 2015-7-13)
